Graphene and carbon nanotubes

Characterization of D graphene or other 2D molecules with one or few atom layers. Basically, it’s sp2 hybridized carbon atoms. Carbon nanotubes are hollow structures with the walls formed by one-atom-thick sheets of graphene. Graphene is the first two-dimensional (2D) atomic crystal available to us. A large number of its material parameters—such as mechanical stiffness, strength and elasticity, very high electrical and thermal conductivity, and many others – are supreme.
